Dust In Counter Top Finish

SprayMan

Project: kitchen:maple butcher block counter tops.

1. sealed with a lacquer, tinted, vinyl sealer CH.
2. sealer, covered with satin, lacquer CH.
3. problem: lacquer melts into itself. Need to apply a barrier coat(s) because if you rubbed the finish too hard it discolored.
4. Client likes hand applied finishes. Spray too "factory."
Hand applied one coat of Zip Guard over the, with a new 4" Purdy bristle brush.
Material fully strained, silk stocking, ... new and clean very thing.
5. vacuumed area, sealed counter tops area with plastic, sanded/vacumed/tacked/ wiped with clean rag with some thiner/let dry/tack rag again.
6. Being in VT, we masked off floor registers and turned the thermostat way down, so as not to go on.
6. All new material and equipment, brush and buckets.

The result was hair and chunks in the finish. And the result was the same with all new material and applicators.

Any sugestions,
Richard

Let's start at the top. New anything sucks. Bristles fall out and break off. Rollers shed. Hairs are also shed by you all of the time. With the care that you have seem to have taken, I don't know where the 'chunks' are coming from. Stacking up your lack of knowlege, I'm guessing that it is not cleaning brushes properly. Are you using any reducers?

no reducers. and properly stired, not shaken.

New or existing kitchen? Anybody coming and going during drying? Floor and all surrounding cabs vacuumed? Cold air return covered? Sounds like there is a draft coming from somewhere. Never used Zip Guard...can you speed the drying time? I'm assuming you can scuff this out and recoat?

All those hairs and chunks sounds like a lot less "factory" to me, maybe they'll love it!

From the info provided I'd have to agree with teetorbilt, those new brushes tend to shed a lot of hairs.

Spray man,
Possibly your rags you are using are letting loose tiny fibers. not easily seen by the naked eye until dry then theyre standing up. I didnt read what type of species of wood, but if its oak ,the grain is naturaly heavy thus fibers getting caught. Try dusting in an away direction from the high side of the grain same with application of finishes. Another thought is to let the dust in the room settle out before applying more coatings. You may be getting airborne dust settling in while the product is drying.
